Guanyl-specific ribonuclease pgl-1 - E3M3V1 (PGL1_CAERE)


Protein Feature View of PDB entries mapped to a UniProtKB sequence  

  • Number of PDB entries for E3M3V1: 2
Guanyl-specific endoribonuclease which cleaves the phosphodiester bond in single-stranded RNA between the 3'-guanylic residue and the 5'-OH residue of adjacent nucleotide, resulting in the formation of a corresponding 2',3'-cyclic phosphate intermediate (PubMed:26787882). Essential role in male and female postembryonic germline development; maternally provided protein maintains a population of proliferating germ cells and zygotic expression is required for correct oogenesis (By similarity). Together with the P-granule component pgl-3, is involved in the formation of P-granules (By similarity). Together with pgl-3, probably recruits other granule components such as pos-1, mex-3 and glh-1 to P-granules (By similarity). In addition, may act redundantly with pgl-3 to protect germ cells from excessive germline apoptosis during normal oogenesis and development of the two gonadal arms (By similarity). This may in part be through regulating the localization of sir-2.1 which is involved in germ cell apoptosis (By similarity). May protect somatic cells from excessive apoptosis during normal development. UniProt

Subunit Structure
Homodimer (PubMed:26787882). Interacts with pgl-2 and pgl-3; this association is not required for P-granule localization of either pgl-2 or pgl-3 (By similarity). Interacts with ife-1 (By similarity). Interacts with prmt-1; the interaction is direct. UniProt
The RNA-binding RGG-box is required for the recruitment of some P-granule components such as pos-1 and probably mRNA, but is dispensable for granule formation. UniProt

Data origin/color codes
The vertical color bar on the left side indicates data provenance.
Data in green originates from UniProtKB  
Variation data (sourced from UniProt) shows non-genetic variation from the ExPASy   and dbSNP   websites.
Data in yellow originates from Pfam  , by interacting with the HMMER3 web site  
Data in purple originates from Phosphosite  .
Data in orange originates from the SCOP   (version 1.75) and SCOPe   (version 2.04) classifications.
Data in grey has been calculated using BioJava  . Protein disorder predictions are based on JRONN (Troshin, P. and Barton, G. J. unpublished), a Java implementation of RONN  
  • Red: potentially disorderd region
  • Blue: probably ordered region.
Hydropathy has been calculated using a sliding window of 15 residues and summing up scores from standard hydrophobicity tables.
  • Red: hydrophobic
  • Blue: hydrophilic.
Data in lilac represent the genomic exon structure projected onto the UniProt sequence.
Data in blue originates from PDB
  • Secstruc: Secondary structure projected from representative PDB entries onto the UniProt sequence.
Sequence Mismatches It is now possible to see information about expression tags, cloning artifacts, and many other details related to sequence mismatches.
Icons represent a number of different sequence modifications that can be observed in PDB files. For example the 'T' icon T represents expression tags that have been added to the sequence. The 'E' icon E represents an engineered mutation. However, besides these two, there are many other icons. For more information about the meaning and exact position of a sequence modification, move the cursor over the icon.
